MPM’S PROVEN CPSS

What is CPSS? — The MPM Cathodic Protection Survey Sys-tem (CPSS) is our proprietary PC-based CP data collection system which can be utilized either with ROVs, divers, or in our towed fish configuration. CP data is collected and stored on the CPSS computer, while CP values are automatically overlaid on the ROV or diver video in real time.

How does CPSS cost less? — When conducting a jacket survey utilizing the stab/ground technique, the ROV must stop the general fly-by inspection every time a CP reading is taken. This results in spread delay approaching 10-minutes per stab location. Assuming a typical spread cost of ~$60k per day, the resulting cost can be greater than $400 per CP reading . . . CPSS data is collected without interruption of the general fly-by inspection work by utilizing a surface ground wire to the structure. The CP data is collected electronically and is overlaid on the ROV video in real time.

CPSS DATA COLLECTION

Typical CP Data

Stab Probe Survey: Primary Nodes Only

14 CP readings

CPSS Survey: All Major Members, ends and midpoint 157 CP readings

During platform surveys, the system utilizes a surface ground wire between the CPSS con-sole and the structure being inspected.

The surface ground technique allows continuous data collection throughout diver or ROV sur-veys without the requirement of stopping and grounding the CP system at each location.

CPSS eliminates the cost of the entire spread waiting for each stab potential reading.

MPM’S CPSS is available in a towed fish configuration to perform close interval pipeline surveys at speeds up to 5-knots utilizing the trialing wire technique. CP sample rates are typically set at 5 samples per second, which (at 5-knots) provides cathodic protection values every 1.6-ft along the pipeline. CPSS simultaneously records CP values from 2 reference electrodes along with navigation coordinates, depth, date, time, and time stamped MPM operator comments.

PIPELINE INTEGRITY AT A LOWER COST

Towed fish survey speed is typically 5-times faster than an ROV survey. The towed fish system can be deployed with a much smaller and more economical support

spread than required for ROV operations. Inland/Shallow surveys can be conducted from an inflatable or air boat with our weather re-

sistant system.

The tow fish configuration utilizes a Side Scan Sonar body retrofitted with MPM electronics, and two Ag/AgCl reference electrodes and is

applicable to 550fsw / 167m.

The ROV is equipped with the MPM CPSS elec-tronics bottle (working depth 6900fsw / 2100m),

two dual Ag/AgCl reference electrodes, and ground stab probe as pictured above.

CPSS is built around a rack mount server grade computer with raid array, and built in UPS.

Our proprietary windows based software

can collect potential data at up to 25 samples per second and import navigation positions in real time.

In the ROV or diver configuration, the CP

and navigation data can be overlaid on ROV or diver video in real time.

CPSS can be equipped to perform EFG

surveys in ROV pipeline mode.

ADVANTAGES OF USING MPM: LEVEL 2-4 API RP 2SIM UWI’s INTEGRITY AT A LOWER COST

Qualified Personnel - MPM project planning and onsite personnel are not simply “data recorders”. Our personnel are extremely familiar with facility construction, repair, and inspection operations.

Comprehensive - Rather than using a canned database, MPM tailors its inspection and

reporting system to match the individual facility and associated scope of work. Inspection Optimization - Our pre-project set up can and should include review of

previous UWI data vs the proposed scope of work. Review of accessibility/interferences, flooding plan & previously identified flooded members vs proposed FMD, repairs, etc. ensures that proposed inspection locations will deliver valuable data without wasted spread time or wasted onshore personnel resources.

Cathodic Protection Data - Data is collected throughout the flyby inspection without

spread delay and is automatically annotated on the video recording. Potentials are collected at each end and the middle of each member inspected which allows assessment of the cathodic protection system’s remaining life.

Results - Utilizing

our system and personnel will result in cost effective field operations, and accurate detailed reporting.

On Screen CP Annotation


CPSS can log/record 25-samples per second; however, 5-samples per second are preferable and typically adequate.

CPSS logs potentials from up to four (4) reference electrodes with +5 mV accuracy (two

proximity / stab, and two EFG), and is capable of constant and or event based data logging. All data is time stamped aiding in post processing and reporting. Comments (disc number, physical location, anode, riser, debris, start/end span, etc.) are

recorded on an event basis, and are automatically logged to the time the comment entry feature is activated

In pipeline mode (ROV, diver, or towed fish) CPSS receives and logs x-y-z coordinates as

applicable from third party navigation systems via serial string. In ROV or diver mode, CP data can be automatically overlaid on the inspection video in real

time. We are capable of placing the CP overlay anywhere on the video screen, thereby avoiding interference with onscreen pilot aids. CPSS video overlay is compatible with all cur-rent video formats including PAL, NTSC video composite, and HD via HDMI.

CPSS FEATURES

Marine Project Management, Inc. has decades of successful marine construction, inspection, and cathodic protection project experience and is uniquely qualified to serve as prime con-tractor for underwater and topside facility inspections and CP retrofits. MPM provides added value by ensuring coordination and functional interfaces between all support services and facility personnel from planning through implementation and reporting. As prime contractor, MPM requires: a scope of work; facility schedule; facility drawings (preferably updated as-built); an anomaly list and previous reports if available; logistics and operations contact da-ta; and a client project advocate.

Towed Fish Survey - The operator or prime contractor will need to provide the scope of work, navigation pre-plots, DGPS surface navigation equipment and personnel, serial navi-gation coordinate output in NEMA183 format, a suitable survey vessel and crew, along with logistics and mobilization support.

ROV Pipeline Survey - The operator or prime contractor will need to provide all items

listed in the Towed Fish requirements along with subsurface navigation, ROV spread, and ROV access for the CPSS system. The CPSS ROV interface requires a continuous isolated ground along with RS 485 from the ROV van to an accessible external connector on the ROV, an accessible external power connector on the ROV supplying either 12-34VDC at 1.1-amp or 100-115VAC 50/60-Hz at 700-mA, payload and space capacity of 8-lbs x 8-in D x 17-in L, and live video feed between the system and the topside recorders.

ROV Structural Survey - The operator or prime contractor will need to provide all items

listed above with the exception of the navigation spread.
